FUEL REQUIREMENTS
This engine is designed to meet all
emission regulations, and provide
satisfactory fuel economy and
performance when using
high-quality unleaded “Regular” gasoline
having a posted octane number of 87 as spec -
ified by the (R+M)/2 method. For optimal
performance the use of 91 or higher octane
“Premium” gasoline is recommended in these
engines.
While operating on gasoline with the required
octane number, hearing a light knocking
sound from the engine is not a cause for
concern. However, if the engine is heard
making a heavy knocking sound, see an
authorized dealer immediately. Use of gaso -
line with a lower than recommended octane
number can cause engine failure and may void
or not be covered by the New Vehicle Limited
Warranty. Poor quality gasoline can cause problems
such as hard starting, stalling, and hesitations.
If you experience these symptoms, try another
brand of gasoline before considering service
for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “refor
-
mulated gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom -
mended. Properly blended reformulated gaso -
line will provide improved performance and
durability of engine and fuel system compo -
nents.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol. Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may
void or not be covered under New Vehicle
Limited Warranty.
Maximum permitted loads

– Front axle 2,579
– Rear axle 2,976
– Total 5,423
Maximum load on roof 165 lbs (75 kg)
1. If special equipment is fitted the empty weight will increase and consequently the payload will decrease in relation to the maximum permitted loads.
2. Loads not to be exceeded. The user is responsible for arranging goods in the luggage compartment and/or on the load platform within the maximum permitted loads.
Weights (lbs)2.9L engine
CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more than
15% ethanol (E-15). Use of these blends
may result in starting and drivability
problems, damage critical fuel system
components, cause emissions to exceed
the applicable standard, and/or cause the
Malfunction Indicator Light to illuminate.
Please observe pump labels as they should
clearly communicate if a fuel contains
greater than 15% ethanol (E-15).

CNG And LP Fuel System Modifications
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system compo-
nents. Problems that result from running CNG
or LP are not the responsibility of the manufac -
turer and may void or not be covered under the
New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricar -
bonyl (MMT) is a manganese-containing
metallic additive that is blended into some
gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage
beyond gasoline of the same octane number
without MMT. Gasoline blended with MMT
reduces spark plug life and reduces emissions
system performance in some vehicles. The
manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT
content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask
your gasoline retailer whether the gasoline
contains MMT. MMT is prohibited in Federal
and California reformulated gasoline.
Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have these additives will help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in mini -
mizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent Gasoline is recommended.
Visit
www.toptiergas.com
for a list of TOP TIER
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or similar
ingredients. These can harm fuel system
gasket and diaphragm materials.
Fuel System Cautions

NOTE:

Intentional tampering with the emissions
control system can result in civil penalties
being assessed against you.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the cata -
lytic converter to overheat. If you notice a
pungent burning odor or some light
smoke, your engine may be out of tune or
malfunctioning and may require imme -
diate service. Contact an authorized
dealer for service assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
